Answer:

  x = 22°

Step-by-step explanation:

The interior angles in a triangle total 180°.

  x + a + 90° = 180°

When we subtract 90° from both sides of this equation, we find ...

  x + a = 90° . . . . . . . . the acute angles are complementary.

  x = 90° -a = 90° -68°

  x = 22°

Answer:

B. 2^10

Step-by-step explanation:

2^3 is the same as 2 × 2 × 2 which equals 8, and 2^7 is the same as 2 × 2 × 2 × 2 × 2 × 2 × 2 which equals 128.

8 × 128 = 1,024

Now we just figure out which option also equals 1,024.

A. 2^-4 = 1/16 or 0.06

B. 2^10 = 1,024

Answer: 16 total starbursts.

Step-by-step explanation:

If 25% were pink, then 75% aren't pink.  Let x be the total number of starbursts.  We know that 75% of x = 12 (the ones that aren't pink).  There is insufficient information to determine whether there is even one red starburst.

0.75x = 12

x = 12/(3/4)

x = 48/3

x = 16

There are 16 total starbursts:

25% are pink = 4 pink starbursts

75% aren't pink = 12 non pink starbursts

Total of 16 starbursts.

We can't answer how many were red.  We aren't given any indication that there is even one red starburst.  All we know is that 12 are not pink.

Answer:

When w = 8, w² - 4w - 2 = 30.

Step-by-step explanation:

w² - 4w - 2

Substitute value w = 8.

8² - 4(8) - 2

Square 8.

64 - 4(8) - 2

Multiply -4 and 8.

64 - 32 - 2

Subtract 32 from 64.

32 - 2

Subtract 2 from 32.

30.

Answer:

[tex] = > {w}^{2} - 4w - 2[/tex]

[tex] = > {8}^{2} - 4(8) - 2[/tex]

Answer:

The expression that represents the sale price of the shirt is p-0.15p.

Given that,

He wants to purchase the shirt i.e. on the sale for 15% off on the regular price.

The regular price should be p dollars.

Based on the above information, the equation should be  p -0.15p

Here the shirt price should be multiplied with the discount and then subtract it.

Therefore we can conclude that the expression that represents the sale price of the shirt is p-0.15p.

Answer:

x < -5

Step-by-step explanation:

x + 3 < -2

- 3 - 3

_________

x < -5

On the number line, the values of x are on the left side of -5 where -5 is not included and this can be determined by simplifying the given inequality.

Given :

Inequality  --  (x + 3 < -2)

The following steps can be used to graph the solution of the given inequality:

Step 1 - Write the given inequality.

x + 3 < -2

Step 2 - First, simplify the given inequality. Subtract 3 on both sides in the above inequality.

x + 3 - 3 < -2 - 3

x < -5

Step 3 - So, the interval of x is given by ([tex]-\infty[/tex], -5).

Step 4 - On the number line, the values of x are on the left side of -5 where -5 is not included.

So, the correct option is a).

Answer:

  2 colas and 4 hot dogs

Step-by-step explanation:

We presume the units of total satisfaction are additive for the two food items.

The maximum number of colas Joe can buy with his $8 is $8/($2/cola) = 4 colas. Since a cola costs twice what a hot dog costs, Joe can give up 1 cola and buy 2 hot dogs. Possible purchases of (colas, hotdogs) for $8 can be ...

 (0, 8), (1, 6), (2, 4), (3, 2), (4, 0)

Of course, either the number of colas or the number of hot dogs (or both) could be less than these values.

The corresponding satisfaction units are added in the attached table. These combinations are highlighted in green. The maximum number of satisfaction units is found to be for 2 colas and 4 hot dogs. (49 satisfaction units)

Step-by-step explanation:

Answer:

3 hours 30 minutes

Step-by-step explanation:

First hour,

All cost, $11.50+$2.50 =$14

remaining charge, $20.25-$14 =$6.25

partial hour,

$2.50 ÷ 2 = $1.25

remaining hour,

per hour, $6.25 ÷ $2.50 = 2.5 hours

total hour rented,

1+2.5 = 3.5 hours

or

0.5 × 60 minutes = 30 minutes

3 hours 30 minutes

3.5 hours was the bicycle rented.

Two or more expressions with an Equal sign is called as Equation.

Given,

Transportation rental company charges $11.50 for a bicycle rental, plus an additional $2.50 per hour that the bicycle is rented

11.50+2.50x

Partial hour rentals are allowed

The total charge for a certain rental is $20.25.

All cost, $11.50+$2.50 =$14

remaining charge, $20.25-$14 =$6.25

partial hour,

$2.50 ÷ 2 = $1.25

Remaining hour,

per hour, $6.25/$2.50 = 2.5 hours

Total hour rented, 1+2.5 = 3.5 hours

Hence, 3.5 hours was the bicycle rented.

Answer:

y = 6/8x - 3/2

Step-by-step explanation:

In this case, since we don't yet know the exact fraction for the y-intercept, we will find the slope first.

To find slope, we will simply start at the first point that is given to us on the graph, and then count the units up and over until we reach the second point. (Remember rise/run)

Our slope is 6/8, because we went upwards 6 units and to the right 8 units.

Now, in order to find the y-Intercept, we will use the point slope formula⤵⤵⤵

[tex]y - y _{1} = m(x - x _{1})[/tex]

We will plug in one of the points that the line passes through. In this case we will use the first given point. The coordinates of the point are (-3,-2).

y - (-3) = 6/8 (x- (-2)) or we can just simplify this to:

y + 3 = 6/8 (x + 2)

To solve this, first distribute 6/8 among everything inside the parenthesis to get

y + 3 = 6/8x + 3/2 (6/8 × 2 = 12/8 then simplify to 3/2). Next we will subtract 3 on both sides to get

y = 6/8x - 3/2.

And there we go, we're done. Hope this helps you :)
